What impact will climate change have on malaria?

Climate change could make a number of infectious diseases worse. I expected malaria would be one of them.

That’s concerning, given the huge global burden that it already carries: it kills almost half a million children every year.

But a more complex story emerges from the scientific literature. One where rising temperatures could actually reduce the burden of malaria in some areas, while making it worse in others.

What impact has climate change already had on malaria? Will it make the global fight against it harder or easier in the future?

These are the questions that I want to answer here.
